PNEUMATIG BOBBIN OONVEYER FOR MILLS.

APPLIGATIONFILED MAY 2.1906.

PATRICK J. HANLON, or Lnreiisraa: t issrHU E 17 '0 (alt whom it may concern.-

Be it known that 1, Fusion J. HANLON, a citizen of the United States, residing at Leicester, in the county of .VVorcester and State of Massachusetts, have invented a new and useful Pneumatic Bobbin-Conveyer for Mills, 7 of which the following is a specification.

These conductors are connected at'theirup- -85 My invention relates to a bobbin-conveyer adapted to receive bobbins from the several parts of one or more weaving-rooms and convey them without interference to the spindleroom or any other desired part of the mill.

The principal objects of my invention are to provide means whereby such a conveyer can be efficiently operated; to provide means whereby the bobbins can be dropped into-the guard against any interference between one drafts ordinarily encountered in conveyers of this character, which are extremely dangere .ous in case of lire; to provide an efficient means for discharging the bobbins from the conveyer without interfering with the passage of air therefrom,'and togenerally improve the construction and operation of con veyers of this character.

Reference is to be had to the accompanyin g drawings, which illustrate a preferred embodiment of my invention, and in which Figure 1 is a side elevation of a conveyer built according to my invention and showing one way in which it can be located in the mill.

Fig. 2 is a side elevation of a portion of the conveyer, illustrating the manner of depositing the bobbins therein. tion of a short bend in the conveyer. Fig. 4 1s a side elevation of the discharge device, and Fig. 5 is an end elevation of the same.

The pneumatic conveyers which have heretof ore been designed for the purpose of carrying the so-called cartridges and other paekages containing articles have been in general of a very simple construction, as these cartridges were especially designed for use in this manner, and eonse uently the problems involved were reduce to comparatively simple Fig. 3 is an eleva-' per ends to vertical tubes 12, having hoppers 13 distributed about the weaving-room in convenient places to receive-the bobbins. The tubes 12. are'of such size as topermit," yThe -go only one bobbin to descend at a time. I conductors 11, it will be'noticed, are provided; 9 with connections entering the tubes 12,.and

fitting the lower ends of thesame and withsa slanting surface 14 extending undereaehofz Q from-the rear thereof. This 5 the tubes 12 slanting surface is suflicient to throw out the. head or other end of the bobbin as; it comes 10 in parallelism therewith. a p 1 I The conductor is elongated at its lower end sufficiently'to permit the bobbin to lie at full length therein above the tube 10, so, that if.

when a bobbin enters the conductor. another bobbin is passing along the tube 10 the upper" one will rest upon it and permit the'lower bobbin to pass-through the tube taking the upper one with it. "The upper" bobbin will then fall down into the tube and 1 10 be carried'along by the current of air which is furnished by means of a fan 15 or any other 1 out the conductor will engage one of the headsand hold it back until the other has passed along sufliciently tolet the second bobbin fall into the tube 10. p

l The main tube preferably extends along thetop of theroom below the-weaving-room just below the ceiling and is supplied with air, as has been. stated, bya fan whi'ch receives the .wall of the building. .The main conveyer-tube, passing, as it does, from the weaving-room to a spinning-room, which is usually on another floor, must be provided with bends to permit the bobbins to freely pass th'rough'it, changing direction as often as may be necessary. It 'is preferable, also, to have these bends as short as ossible, and for this pur ose I have provide anordinaryrounded su ace 17 on the outside of'each bend, form ing a continuation of the two parts of'the main tube which it connects. .Instead of carrying a curved tubearound the bend I have. rovided a flat surface 18 opposite the I roun ed surface 17,which, while guilding the bobbins, will not interfere with their turning in the bend and permits them, in fact, to turn at a ver short angle. By the use of this imroved end-or elbow the conveyance of the 'obbins is secured with a reduction in ,fric- 3 5 tion and an increase in speed. The-forward end of the bend acts also like the forward end of the conductor 12 to prevent two bobbinheads leaving at once. 7

As was stated above, the air is taken into :40 the conveyer through one of the outer walls g of the building, and it is preferably dis- F charged from it through the same or another g wall. This operation is preferred on account I of the fact that with the ordinary construc- '4 tion of pneumatic convyer a powerful draft is furnished in case offire, which greatly ham- '1 pets the efforts of the fire department m'conrolling. the flames.

In order to discharge the air through the got wallet the building and intercept the bobbins in such a manner that they will remain within the building, I have provided a discharging device compri'sing a skeleton frame 19, flaring from the end of the. conveyer-tube and extending over the space betweenthe end of thisftube and a conical receiver 20. The lower side of the space between the tube grail receiver is open to permit the bobbins to Inside the receiver 20 is a flexible screen 21, which is made of wire-cloth or any other material adapted to ermit the passage of air and. intercept soli articles. Behind the screen 21 isa nozzle 22, which preferably extefids from the wall to dischar e the air out.-

its-supply from atube 16', extending through side the building. If desired, this nozzle may be caused to return to the inlet 16, so that the air will be forcedaround the conveying- .tube without passing to the outer air or ,re-

ceiving any additions from it. The same form of nozzle is used in both cases. I

Itwill be seen that by theemployment of the principles above set forth, whether in the form shown or otherwise within the scope of the claims, the pneumatic conveyer is amply adaptedfor the purpose of conveying bobbins.

in mills.

I am aware that many modifications may be made in the form of ap aratus illustrated without departing from t e scope of my invention as expressed in the claims. Therefore I do not wish to be limited to the particular construction shown; but i What I do claim, and desire to secure by Letters Patent, is' I 1.

3.
